` BRUSH.

To all whom it may concern.'

"Be it `knownthat I, THOMAS F. BARRY, a 4citizen of the United States, anda resident of Newark, in the-county of 'Essex and State 0f New Jersey, have invented certain new and' useful `1mprovements"in Bru-shes, of which the following is azpecification.

-The invention relates to improvements in brushes, more especially` ofthe `kind `employed in calsomining, paintingandI thenlike,

and it consists in the novelA features and structure hereinafter'describ'ed and particu- Vvlarly pointed out in the claim. My invention ismore particularly applicable to and useful in the manufacture of broad fiat brushes comprising a -handle, a bunch of bristles secured at their vinner ends by vulcanized rubber, forming a knot, a metallic band closelgTlv encompassing said knotfand a `metallic band or ferrule secured to the shank of the handle" and `also to. saidbunch `of bristles and 'connectingthe two together. A special object of thel invention is to provide adequate means whereby the. bunch `of bristles may be efliciently secured. to the handle, many difliculties having been encountered in thussecuring broad flat bunches to broad flat handles. In practical use the strain on the broad flat bunch of bristles is consider- ,able'and the tendency is sometimes to wrench the bunch v'fromthe handle. The handles are `made of'wood andv the users of these brushes sometimes leave'the brush standingin water or calsomine overnight, and thisy results in the swelling of the handle and inthe breaks ing away or loosening ofthe same fromthe means securing the handle to the bunch. Durf ing a great deal of the timethe brush is in use the handle is subjected ,to moisture which tends to impair the eiliciency ofthe means securing 'the handle to the bunch and to otherwise depreciate the brush in respect to its durability. In accordance with my invention I speciall construct the band which encompasses the kn tles and the band or ferrule which encompasses the shank end of the handle and said band on the knot so that they may have special interlocking relation and that the band or ferrule on the handle, the band on ,the knot and the knot itself may be eflectually secured together by rivets extending transversely throu h the same and properly headed at both en s at the outer side of the band or ferrllle 0n the handle, washers being apot on the bunch of brisi y Specification of Letters `Patent. i s Patliteidsept. 2,1919. appueaton inea september 18,1914. serial Netware.A

from` the detailedfdes'cription hereinafter presented, referencebein `had to the accompanyingdrawings,in w ich: Figure 1 is a front levation` of a brush constructed in accordance with and embodying my invention Fig. 2 is a vertlcal section through the same on the dotted line 2-2 of Fig. 1f;

" Fig. 3 is aA detached perspective view of the band or ferrule which connects the handle and bunch of bristles together;

Fig. Llis a detached perspectiveview of the inner band which encompasses the knot on the bunch of bristles, and

.Fig.,5 is a detached perspective view of one of the rivets, with the'washers for the endsthereof, which are utilized for securing the 'bunch of bristles and the'band or ferrule on the handletogether.''`y l In the drawings, 10 -designatesjthe'handle of the brush, 11 the bunch of bristles,12 the knot formedon the upper end of said bunch, 13 the inner'metallic band closely encompassing the said knot and 14 the metallic band or ferrule which encompasses the band 13 and' the shank end of the handle and is secured both to the handleandbunch. s

The handle 10l is of customary form 'and construction, and the `bunch -11 is in itself of known character, theknot Y 12 being formed bydipping thegend "of the bunchin soft rubberA and 'thereafter'-- vulcanizing the rubber 'by standing the knot endk of the brush on a' steam orotherheated table. The bristles at the knot end fthe bunch are held together during the vulcanization by means of the bands-13 which is slipped down upon the knotend of the bunch after the said end has been vdipped in the soft rubber. AThe band 13 is of the special configuration shown, havingin each ofits sides an external elongated groove 15y in which is interposed a` series ofsockets 16,`said groove and
